While roughly half of the world's hydropower potential is in the developing countries, totaling about 1,200 gigawatts, only 10 percent has been tapped, a World Bank study indicates. The study forecasts that over the next decade about 100 gigawatts of hydro capacity will be added in about 60 developing countries. Developing countries in Asia, Latin America and North Africa are attracting the most attention from U.S. and Canadian hydro engineering firms. These nations are developing hydroelectric facilities as part of their long-term industrial development plans.
